It is very important to keep the gas wells unloading, decrease production cost, and increase recovery factor. Therefore it is necessary to determine the critical liquid carrying flow rate. Through the comprehensive investigation and evaluation of the current models, applying the knowledge of two-phase flow, a computation method of critical liquid carrying flow rate at high GLR is recommended, and presented a new critical liquid carrying flow rate model at low GLR. The field application indicates there is a good agreement between the calculation results of the method and actual production data.%建立合理的携液临界产量的计算方法,确保生产气井连续不积液生产,对于节约生产成本、提高气田产量和采收率都具有重要作用.以产水气井实际生产状况为基础,运用气液两相流理论,提出并分别阐述了高气液比和低气液比条件下携液临界产量模型的原理和计算方法.结果表明,所建立的方法具有良好的有效性,对气井合理生产制度的制定有一定的指导意义.
